MOLD.

' i Be'it known that I, Fnnimnicx A. FELD- iiniur, a citizen of the United States, residersey, have invented certain new and useful Improvements in Molds; and I do hereby, declare the following to be a full, clear, and exact description of the infvention, such as will enable others skilled in the art to which it appertains to make and f use the same, reference being had to the acreference marked t ereon, which form a provcments in'molds'; and, the invention' has reference, more particularly, to a novel companyig 'dra'win s, and tov charactersv of part pf this specification. i

This invention relates, generally, to immold and the mold-sections therefor,rwith a view of providing reinforced paper mold, or a paper-lined, or a metallically reinforced pa ermold and the mold-sections therefor.

y present invention has for its principal object to provide a mold of the general character and the general arrangements and con- I structions of the parts thereof, as will be hereinafter more full, set forth, with a View of providing a simp y constructed and eiii- V ciently o erating mold, in which the molten metal, w en poured int-o the mold, does notbeconie suddenly chilled and will not rap- :idly 'solidify so as to produce an uneven or imperfect casting; and, the invention has for itsfurther object to provide a moldand the mold-sections therefor, .which can be most cheaply made, and may be -used over and over, to provide great .economy in casting.4

My present invention has lfor its further object to provide a reinforced'paper mold of the general character hereinafter more particularly set forth, which has' flexibility and resiliency, and which is especially adapted for use in producing metallic matrices or grids of a metal which fuses readily at a lonr temperature, such as are used in the methods of producing automobile radiators made by the processes of electro-deposition, inrwliicli metal, as copper, is .deposited upon the matrix or grid, and wheii'completely deposited, the matrix or grid being melted out of the deposited copper at alow temperature, so as to leave a complete and hollow shell or casing of the electrolytically deposited i copper.

" Other objects of the present invention will be clearly obvious from the following detailed description of the pi'esent invention.

. With the various objects of the present invention in view, the said invention con- `Vsists, primarily, in the novel mold and moldsections therefor, more fully set forth in the following specification, and then' finally cin- Y bodied iii the clauses of the claim which is 4appended to and which fornisan essential part of this specification. v The invention is clearly illustrated in the accompanying drawings, in which Figure l is a face view of one of the sepa-` rable lmold-sections or halves of a mold made according to and embodying the priiiciples of the present invention, said view representing in face view, the papenportion of the mold; and Fig. 2 is 'a transverse sectional representation of a. mold, the moldsections'thcreof being made of/paper, reinforced u-pon the back with other layers of.

paper, said view being made on an enlarged scale. Figs. 3 and 1 are transverse sectional representations of two modified vforms of molds embodying the principles of the resent invention, said views being also ma e on an enlarged scale'.

Similar characters of reference are emloyed in the said above described views, to indicate corresponding parts.

Referring now to the said figures of the drawings, it will be` seen that the mold is preferably made in two separable sections or halves, each section comprisin a member or element 1 made from suitab e organic material, as paper, wood pulp, :iper-pulp linen, or the like, which are suita ly formed with raised portions, as 2, and depressed portions, as 3, 4 and 5. It will be understood, however, that these raised portions and depression are not necessarily of the configuration here shown in the accompanying drawings, but that raised portions and depressions of any other suitable configurations may be used, whenever desired.'

In the forni of mold shown in Fig. 2 of the drawings, and which is entirely made of paper, it will be seen that the paper mold sections or members 1' are reinforced upon the back with other layers of paper, as 6, thev connected being? pressed together, or:

otherwise assembled, with the outer surface or face of each inold-section being made flat, as at 7. i i

In Fig. 3 of the drawings, the referencef character? 8 `indicates a pair of-nietal plates or sections,` each plate or section 8 being Vmade with?n correspondingly formed raised K portions,..as 9and depressions, :is-10, 11

and 12, with which the respectiveraised por-` -1 from an inspection of said Fig. 4.

rIo provide a complete mold for casting, the two mold-sections thus produced, andas shown in said Figs. 2, 3 and 4;, have their v'faces upon which the raised portions are formedfplac'ed face to face, in the manner 'illustrated in said Figs. 2, 3, and t, the moldsect-ions being brought into their registering relation preferably by means of suitably formed and suitably disposed dowels or pins, as'll.' Any desirable number of such registering mold-sections can be placed side by side and then assembled in any suitable form of holding means or clamping frame, so as to permit of the pouring of the molten metal into said assembled molds. After the casting have been completed, the several molds are removed from such holding means or clamping frame, the registering molde sections of each individual mold being easily and `quickly separated for the removal of the completed casting, as will beclearly understood. 4. l f

In practice these molds areto be used, preferably, for the purpose of producing matrices or grids of a metal'Y which fuses at a low temperature, and for that reason the metal plates or sections 8, when used, may be made of a similar metal which isof cheap manufacture; it be understood, however, that the said members orsections 8 may be made of anyother suitable material.-

The main advantage in makingmold-seotions of paper, as herein provided, is that each mold-section is capable of a cert-ain i flexibility and resiliency so that the registering raised portions of any two adjacent v mold-section when clamped togetherwillbecome tightly pressed together 'into intimate contact, so that positively tight jointswill be produced, and a perfect castingof the' metal which is poured into the assembled,

mold-sections willbe theresiilt, as will be clearly evident. I am aware, therefore, that my present invention is capable of some changes as to the general arrangements and4 combinations of theseveral parts; as fwell as to the material and general configuration and shapes of. the said parts. Hence, ,I do

not limit my present invention toV the exact arrangements and combinations of the said parts as described in the foregoing specification, except as defined in the claims which are appended hereto; nor do I confine myself to the exact details of the construction, nor y to the general configuration ofv the said parts, as illustrated in the accompanying drawings.,

I claim Y l. A moldcomprising a pair of mold-sectionsA having resiliency, ea-ch mold-section being made of organic material, .and/each mold-section having a reinforced face.

2. A mold comprisinga pair of mold-sec tions having resiliency, each\ mold-section.'

being made of organic material, and each l mold-section having a reinforced face comff bined with a netting or meshfabric within said reinforced face.

3. A mold comprising an outer section or element of metal, and an inner sect-ion or l element of paper.' 4. A mold comprising an outer section orelement of metal, and an innerysection or element of paper, combined with a netting n or mesh-fabric within said metal section or element.

5. A mold comprising a pair of separable members, each member consisting of a section or element of metal and an inner section or element of paper, combined with a netting or mesh-fabric within said metal section or element.

6. A mold-member or half made o f'organic material, said mold-member having a reinforced face, combined with a netting .or

mesh-fabric within said reinforced face.`

7. A mold-member or half ofniet-al, and a section or elementof paper upon one off the faces of saidmetal'mold-member or half. In testimony, that I claim the invention set forth above I have hereunto set myhand this 13th day of October'1911.
